Late evaluation of glomerular filtration rate, proteinuria, and urinary acidification after acute tubular necrosis.

Fourteen patients were studied 2 to 36 months after acute tubular necrosis. It was observed that 43% of the patients had decreased glomerular filtration rate. These patients were older and had lower urinary excretion of ammonium and titratable acidity. Proteinuria greater than 150 mg/day, without reaching a nephrotic level, was found in 92% of the patients. The presence of oliguria, the demand of dialysis, and the acute tubular necrosis etiology were not statistically different among the patients who recovered their glomerular filtration rate either totally or partially.

Use of dextran 70 to estimate peritoneal lymphatic absorption rate in CAPD.

Peritoneal lymphatic absorption rate (LAR) in 15 patients on a CAPD program was measured by estimation of the disappearance of dextran 70 from the peritoneal cavity. The LAR was 1.03 +/- 0.45 ml/min. The cumulative lymphatic absorption, cumulative net transcapillary ultrafiltration, calculated net ultrafiltration (CUF) and measured net ultrafiltration (MUF) at 4 h exchange were respectively: 261 +/- 127 ml, 694 +/- 134 ml, 446 +/- 135 ml and 409 +/- 136 ml. Calculated and measured net ultrafiltration didn't differ significantly. An inverse correlation between MUF and LAR and a positive correlation between MUF and the ratio for dialysate glucose concentration at 4 hand dialysate glucose at 0 h (G4/G0) were observed (r = -0.522 and 0.547, respectively, p < 0.05). The multiple correlation coefficient between the MUF and LAR plus G4/G0 was higher (r = 0.617, p < 0.05). Peritonitis and the presence of diabetes didn't interfere with LAR. We have concluded that lymphatic absorption plus peritoneal transfer rate of glucose are important determinants of intraperitoneal volumes and that dextran 70 is a useful marker to measure lymphatic absorption.

An outbreak of nosocomial Legionnaires' disease in a renal transplant unit in São Paulo, Brazil. Legionellosis Study Team.

From June 1989 to March 1990 there were eight cases of Legionnaires' disease caused by Legionella pneumophila serogroup 1 in a renal transplant unit. There were seven cases of pneumonia and one case of pleural effusion. A study was conducted to identify the source of the outbreak. Legionella anisa was cultured from tap water. Twenty-seven staff members of the unit were serologically tested and antibody titres were positive in two. The probable source of infection was the potable water system. Control measures were hyperchlorination and heating of the water, after which there were no further cases during 5 months' follow up. We believe this is the first reported Legionnaires' disease outbreak in Latin America.

Immunological tolerance in human transplantation. The possible existence of a maternal effect.

We analyzed data from 93 patients who received a kidney graft from their parents; 55 were transplanted with a kidney from their mothers (Mat.) and thirty-eight from their fathers (Pat.) The Pat. group has shown a better graft and patient survival as well as long-term renal function when compared with the Mat. group. This pattern was more evident with time. Long-term graft function assessed by creatinine levels also showed differences between the groups, favoring the Pat. group. The results are interesting since recent reports have claimed a tolerance developed by the individual to noninherited HLA antigens of their mother.
